Cmotion Mainstation MST1
€0.00*
High-load, ultra compact power solution for film sets
Five hot-swappable modular inputs
Six regulated outputs up to 1000W
And a three bay battery charger
Introducing the ultimate power solution for all your power needs. This powerful system comes equipped with five hot-swappable inputs and six regulated, always-on outputs, providing up to 1000W of power. With two external inputs that are prioritized over the on-board batteries, you can now travel worry-free with untested foreign equipment that may have conflicting wiring.
With built-in over and under-voltage protection, as well as overcurrent monitoring, this power solution ensures safe and reliable operation. Reverse current from a higher voltage input source is blocked, making it ideal for use with remote heads, underwater rigs, or any other scenarios where hot-swapping is critical.
The external inputs are independently rectified, providing the correct polarity to the downstream equipment. This power solution has no crosstalk, built-in protection, polarity rectification, complete voltage range, and is hot-swappable, making it an ideal solution for any setup.
All channels are independent, ensuring that the batteries are not connected together. You can use any battery mount usually used on set via the universal battery plates, making it even more convenient. And if needed, 14V and 28V batteries can be used at the same time.
The input currents are digitally controlled for optimal discharge rates and timings, making this power solution the ultimate choice for any professional setup. With this power solution, you can rest assured that you have the power you need, when you need it, and with complete reliability.
